WINDOW-CONTROL MECHANISM.
Application filed July 9, 1923.
To all whom itmag concern:
Be it known that 1, CHARLES FoRcnnsoN,
a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a new and useful lVindow-Control Mechanism, which invention is fully set forth in the following specification.
This invention relates to window raising and lowering mechanisms for use particularly in connection with closed vehicles and has for its primary object the provision of .a simple and inexpensive mechanism of this character which is capable of being easily and quickly installed, is composed of comparatively few parts and is easy to manipulate. Further objects and advantages of the invention will be apparent from the following detailed description thereof.
While the invention in its broader aspect is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,
Fig. 1 is an inner side view of a window casing or frame with a mechanism embodying theinvention associated therewith, with parts broken away, and with the window in partially lowered position. Fig. 2 is a 30 vertical section thereof on the line 2-2 in Fig; 1. Fig. 3 is an enlarged detail of a portion of the control means for the window raising and lowering mechanism with the means in locked position. Fig. 4 is a section on the line 4-4 in Fig. 3. Fig. 5 is a view similar to Fig. 3 with the parts moved to released position. Fig. 6 is a section on the line 66 in Fig. 3. Fig. 7 is an enlarged detail of the window engaging portion of the mechanism with parts removed. Fig. 8 is a section on the line 88 in Fig. 7. Figs. 9 and 10 are details of a portion of the mechanism with the former in complete collapsed position and with the latter partially raised from such position, the counter-balancing means being removed therefrom, and Fig. 11 is an edge elevation thereof.
Referring to the drawings, 1 designates a window casing which may comprise a door, and is provided with the window opening 2 in its upper portion that is closed by a glass or window 3. This glass when lowered, enters a chamber 4 formed within the lower portion of the casing below the window opening, as is well understood in the art.
Serial No. 650,217.
The means embodying the invention for controlling the raising and lowering of the window 3 is disposed within the chamber 4, and includes a pair of lower links 5 which are pivoted together at their inner ends on a stationary stud 6 secured within the lower portion of the chamber 4 to a side wall member 7 thereof. An upper link 8 is pivotally connected at its outer end to the outer end of each link 5 andthe opposite ends of the links 8 are pivotally connected together by a vertically movable pivot member 9, which is disposed over the stationary pivot 6 and carries a U-shaped or channeled strip 10 in which the lower edge of the window 3 is centrally seated. The links 5 and 8 cooperate to form a lazy-tongs means that is adapted to be vertically extended or collapsed by raising and lowering movements of either pair of links 5 or 8 to effect corresponding raising and lowering movements of the window, as is well understood in the art,
The U-shaped clip 10 is, preferably for lightness and cheapness, formed of sheet metal withthe outer end portions of its legs spaced a greater distance apart than the inner portion of such legs to provide a receiving space for the edge of the window 3. The lower contracted portion of the clip member 10 is vertically notched centrally of its ends, as shown at 11, to receive the enlarged central portion of a pivot member 9, the end portion of the pivot member being preferably reduced to enter apertures in the upper or inner ends of the links 8. The pivot member 9 is retained in the notch 11 of the member 10 by a wire 12 which is inserted through the loop of the member 10 below the pivot and has its ends bent for preventing withdrawal therefrom. This enables the clip 10 to be easily and quickly disconnected from the raising mechanism for the purpose of repair or substitution of either the window or the mechanism.
The control means for the mechanism comprises a lever 15 of bell-crank form, which is fulcrumed at its elbow on a stud 16 projecting rigidly within the chamber 4 from a frame or a' side wall member 17 thereof; The upper arm 18 of the control lever has an extension 19 connected thereto for free limited sliding movements longitudinally thereof, and the upper end of this extension is pivoted'to a slide block 20 that is mounted for horizontal movements in a guide slot 21 provided in the sill strip 22 of the window frame opening 2. A handle 23 is provided on the top of the block 20 in exposed position to facilitate a movement of such handle.
A link 24 forms an extension of the short horizontally projecting arm 25 of the lever 15 and has its inner end provided with a longitudinally extending slot 26 (Figs. 3, and 6) through which the pivot stud projects. A stud 27 projects laterally from the link 24 and normally seats in a notch 28 in the free end of the lever arm 25, being held seated therein by a coiled contractile spring 29 that is connected at one end to a finger 30 on the link and at its other end to a finger 31 on the lever arm 25. The lever 15 is permitted to have limited rocking movements relative to the link 24 suflicient to force the stud 27 out of the notch 28 and to impart a short longitudinal movement to the link 24 relative tothe associated lever arm, such lateral movement being permitted by the slot 26 in the link. The lever arm 25 has fingers 32 projecting from each side thereof in straddling relation to the link 24 and these fingers coact with the respective edges of the link to limit the relative rocking movements of the lever and link. It is thus evident that after the initial movement of the lever 15 in either direction, which movement is independent of the link 24 and for the purpose of imparting longitudinal move-- ment to the link, one of the fingers 32 then coacts with the link to cause it to swing with the lever during its continued movement.
A peripherally notched sector plate 33 is rigidly secured to the window frame me1nher or cross-bar 17 by screws 24 (Fig. 6) and has its notched edge disposed in position to receive a tooth 35 on the link 34 i when the link is in its normal position with respect to the lever 15 as shown in Figs. 1, 3 and 6. The longitudinal movement which is imparted to the link 24 by the initial relative movement of the lever 15 forces the tooth 35 out of locking engagement with the sector plate and renders the window raising mechanism free to be raised or lowered the desired extent by a continued movement of the control slide 20.
The link 24 is pivotally connected at its free end to a draft link 36, which is pivotally connected at its lower end to the connecting pivot 37 of a pair of oppositely extending links 38 which diverge from each other and the pivoted at their outer ends to respective links 5 at a distance from the inner connecting pivot 6 of such links. The distance between the pivot 6 and the points of connection of the links 38 to the links 5 depends on the power which it is desired to exert by a movement of the links 38 on the links5 and also on the length of movement it is desired to impart to the link 36 to give the lazy-tongs means 5, 8 the maximum throw, as is well understood in the art.
The pivot 37 preferably extends through a slot 39 in the link 36 and the lower end of the link is preferably formed with a lip 40 projecting under the inner end portions of the links 38. When the links 5 and 8 of the lazy-tongs means are in substantially complete collapsed position, as shown in Fig. 9, with the lower links 5 in substantially longitudinal alignment, the inner end portions of the links 8 rest on the lip 40 of the link 36 and the pivot 37 is disposed at the lower end of the slot 39. During the initial raising movement of the draft link 36 from this complete collapsed position the lip 40 acts against the inner pivoted ends of the links 8 to start the raising movement of the links 5 and 8, instead of the draft being applied directly to the links 5 by the draft links 38, in which latter case it would be difficult to move the links 5 from their dead center position. During the raising movement of the mechanism the pivot 9 rises much faster than the pivot 37 due to the different lengths of the links 8 and 38, so that when the draft link 36 has been raised sufiiciently to bring the pivot 37 in engagement with the lower end of the slot 39 the links 5 will have been moved from deadcenter position and the lazy-tongs means will then continue its extension movement by reason of the draft applied to the links 5 thereof through the links 36 and 38.
A. counterbalance spring 41 of coiled contractile form is anchored at its upper end, in the present instance, to the sill member 22 of the window frame and is connected at its lower end to the links 5 through the medium of a pair of toggle links 42 which have their inner upper ends connected to the spring and their lower spaced ends connected to the respective links 5 at opposite sides of the pivot 6, and, in the present instance, at points closer to the pivot 6 than. the points of connection of the links 38. This distance may be varied, however, depending on the counterbalancing pull desired to be exerted on the window raising mechanism.
In the use of my mechanism it is only necessary for the operator in raising or lowering the window to grasp the handle-26 and move it the desired distance to the right -01: left along the sill strip 22. The initial movement of the handle 26 rocks the lever 15 to throw the stud 27 out of the notch 28 and thereby impart a longitudinal releasing movement to the link 24 relative to the notched sector plate 33. hen this has been accomplished, one or the other of the fingers 32 on the lever will engage an edge of the link 24 so that during the continued movement of the lever the link will be moved therewith, thereby imparting movement to the draft link 36 and a consequent raising-or lowering of the window by reason of the movement which is imparted to the lazy-tongs means 5, 8. During any movement of the window its weight on the raising mechanism is counterbalanced by the spring 41 and its connection with the mechanism. If the lazy-tongs means is in complete collapsed position, as shown in Fig. 9, the initial raising movement of the link 36 will be imparted to the upper links 8 of the lazy-tongs means by reason of the engagement of the lip 40 therewith instead of being imparted to the lower set of links 5 through the draft toggle links 38, thus preventing the dead-center action which would be occasioned if the initial raising pull on the links 5 was through the links 38 instead of the links 8.
It is found in practice that with my in vention a very slight pressure is required on the control handle 23 to release the locking connection of the link 24 with the sector plate 33 and to raise or lower the window.
I wish it understood that my invention is not limited to any specific construction, arrangement or form of the parts as it is capable of numerous embodiments and changes without departing from the spirit of the claims.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is,
1. In a mechanism of the class described, a frame, a member slidably movable therein, a lazy-tongs means operable to move said member and having a pivotal connection at one end to the frame and connection at its other end to the member, a set of toggle links connected to a set of oppositely projecting links of the lazy-tongs means at opposite sides of the pivotally connected ends of such lazy-tongs links, and a counterbalancing spring anchored at one end to the frame and connected at its other end to the set of toggle links to exert a pull on the lazy-tongs means through the set of toggle links.
2. In a mechanism of the class described, a frame, a member slidingly movable in the frame, a lazy-tongs means operable to impart sliding movements to the member relative to the frame and having a single pivotal connection at one end with the frame and a single pivotal connection at its other end with the member, and draft means connected to one pair of links of the lazy-tongs means and operable to impart extension or retraction movements to the lazy-tongs means and also operable to acton another pair of links of the lazy-tongs means to impart initial starting movement thereto when the lazy-tongs means is in complete collapsed position.
